使用NEST从ElasticSearch中的插件设置analyzer

我的第一个SO帖子！ 我正在尝试为字符串字段设置一个Stempel分析器（波兰语的ES分析器）。我可以通过PUT请求来完成：

{
   "doc": {
      "_source": {
         "enabled": false
      },
      "properties": {
         "file": {
            "type": "attachment",
            **"analyzer": "polish"**,
            "fields": {
               "content": {
                  "type": "string",
                  "term_vector": "with_positions_offsets"
               }
            }
         }
      }
   }
}

而且效果很好。试图通过NEST做同样的事情

 [ElasticProperty(Name = "_content", TermVector = TermVectorOption.WithPositionsOffsets, Analyzer = "polish")]
 public string Content { get; set; }

不起作用，也不要：

            client.CreateIndex(index, b => b.AddMapping<DocInES>(m => m
            .MapFromAttributes()
            .Properties(props => props
                .String(s => s
                    .Name(p => p.File.Content)
                    .Analyzer("polish")
                     ))));

它工作正常，因此.NET正在检测此分析器。 我使用的是ES 2.1.1& NEST 1.7.1

编辑： 从我检查的内容来看，NEST似乎并没有映射在.NET中创建的附件类的属性。它确实映射文档类的属性

[ElasticType(Name = "docInES")]
public class DocInES {
    public int InstitutionId { get; set;}
    public int DocumentId { get; set; }
    [ElasticProperty(Store = true, Analyzer = "polish")]
    public string Title { get; set; }

    [ElasticProperty(Type = FieldType.Attachment)]
    public Attachment File { get; set; }

}

但不是附件类：

public class Attachment {
    [ElasticProperty(Name = "content2", Store = true)]
    public string Content { get; set; }

    [ElasticProperty(Name = "content_type2")]
    public string ContentType { get; set; }

    [ElasticProperty(Name = "name2", Analyzer = "english")]
    public string Name { get; set; }
}

您可能应该检查上的兼容性矩阵

Nest 1.7.1与ES 2.1.1不兼容

请注意：Nest 2.x已发布。非常感谢您的帮助！将尽快使用它，厌倦了创建JSON请求

public class Attachment {
    [ElasticProperty(Name = "content2", Store = true)]
    public string Content { get; set; }

    [ElasticProperty(Name = "content_type2")]
    public string ContentType { get; set; }

    [ElasticProperty(Name = "name2", Analyzer = "english")]
    public string Name { get; set; }
}
